It's been seven years since Dave Winer launched Scripting News, and now we've got millions of blogs on every subject from political commentary to bird watching and even God.
Because you can't define the circulation of a blog in the same way you'd define the circulation of a newspaper, it's impossible to know precisely how many individuals are reading blogs, but the numbers are surely in the millions somewhere. As recently as a year ago, the Pew Internet Project suggested only about 4% of people online were reading blogs. With 75% of American households now online, even if there are only a tiny portion of those people reading blogs, it's still an amazing number. When you consider the projection by the Computer Industry Almanac of 950 million users worldwide in 2004, that's a lot of potential readers, anyway you slice it. As with anything else online, the new and innovative very quickly becomes commonplace, and so I don't think it's too far out of line to expect there to be tens of millions reading blogs by the end of this year.
